Arcam Solo vs NAD separates

Posted this question last week but no responses. :c( So on the
off-chance that someone has an opinion...

I currently have a NAD C320BEE amp, C521BEE CD player and C422 tuner
powering some Kef Q1 speakers. Very nice setup, good sound, fantastic
speakers.
Unfortunately space is going to become a major issue, so I'm
considering trading in the NAD separates for an Arcam Solo to run the
same speakers.

What's the difference in sound going to be like? Arcam say
(unsurprisingly) that the Solo is better than similarly priced
separates, What HiFi says (unsurprisingly) that it separates will sound
better. Anyone had any experience of comparing the two?

Thanks
Nick
